Analyzing earlier makes it so that Postgres has statistics when rewinding the subgraph
It's only maintained in the primary, and there's no point in mapping it across shards
When creating many copies with a shell script, it is useful to have the deployment we are trying to copy in the error message
With recent changes, the status shown was '>' (in progress) for all tables that hadn't finished yet, not just the one being worked on
At the point where we create the postponed indexes during copying, nothing else is writing to the subgraph and we can't be blocking a writer with a normal 'create index'. Since concurrent index creation has to wait for all previous transactions in the database to finish, the concurrent creation can significantly slow down index creation and therefore how long the copy takes.
